Weather Performance & Sealing
The 109 mm Thermal Break Outward-Opening Window combines a thermally broken aluminum frame, high-performance IGU, multi-level perimeter sealing, durable hardware, and reinforced frame connections to provide a reliable solution for residential and commercial building projects.

Structural & Design Features
Concealed Sub-Frame
The system can be configured with a concealed sub-frame and flush-frame appearance on both interior and exterior elevations, providing a clean architectural appearance and reducing visible frame lines.
Insect Screen Sash
The insect screen sash is designed for inward operation and can be fitted with anti-collision corner guards for improved usability and protection during operation.
Corner & Frame Assembly
The frame, mullions, sub-frames, and sashes are assembled using injection-molded corner keys. Two-component structural corner adhesive is injected into the corner joints to improve joint integrity, dimensional stability, and water resistance.
